Description

Technical Field

[0001] This utility model belongs to the field of galvanized door construction technology, and in particular relates to a galvanized door with an anti-derailment limiting structure. Background Technology

[0002] Galvanized doors are doors whose surfaces have been galvanized and are widely used in the construction industry. They serve both protective and decorative functions and are usually made of steel as the base material. Steel has high strength and good processing performance, which can ensure the structural stability of the door. Common types of steel include cold-rolled steel plates and hot-rolled steel plates.

[0003] When installing galvanized doors, it takes a considerable amount of time to precisely align the tracks and pulleys. Over long-term use, due to uneven ground, external impacts, and other factors, the pulleys are prone to derailing from the ground track, causing the door to be unable to slide normally, affecting its use and potentially creating safety hazards. Therefore, there is a need for a galvanized door with an anti-derailment limiting structure. By using pulleys and ball bearings to simultaneously limit the movement, the pulleys can be effectively prevented from derailing, improving the stability of the galvanized door during sliding. Utility Model Content

[0004] The purpose of this invention is to provide a galvanized door with an anti-derailment limiting structure. By using pulleys and balls to limit the movement synchronously, the pulleys are effectively prevented from derailing, thus improving the stability of the galvanized door during sliding and solving the aforementioned technical problems.

[0013] In the following description, embodiments of the galvanized door with an anti-derailment limiting structure of the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates a galvanized door with an anti-derailment limiting structure according to an embodiment of the present invention. It includes a sliding seat 2 fixedly connected to the bottom of a galvanized door panel 1. A ground track 3 is laid below the sliding seat 2. Support frames 4 are provided on the front and rear sides of the top of the inner cavity of the sliding seat 2. Triangular supports 5 are welded to the front and rear ends of the bottom sides of the support frames 4. Adjacent triangular supports 5 are rotatably connected to pulleys 6 via bearings. A track bar 7 is integrally formed on the top of the ground track 3. A fixing frame 8 is welded to one side of the support frames 4. The inner cavity is provided with an adjustment component 9, which includes a hexagonal rotating block 91 rotatably connected to the top of the inner cavity of the fixed frame 8. A threaded pin 92 is welded to the bottom end of the hexagonal rotating block 91. A hexagonal nut 93 is welded to the top of the lifting column 10. The bottom end of the threaded pin 92 passes through the inner cavity of the lifting column 10 and is threadedly connected to the hexagonal nut 93. Limiting pins 94 are welded to the top and bottom of both sides of the lifting column 10. Limiting grooves 95 are opened on the top and bottom of both sides of the fixed frame 8. The limiting pins 94 are slidably connected to the inner cavity of the limiting grooves 95. The cavity, through the adjustment of component 9, in which the hexagonal rotating block 91 and threaded pin 92 work together to thread the hexagonal nut 93, allowing the lifting column 10 to move up and down within the cavity of the fixed frame 8. This, in turn, allows the lifting column 10 to drive the ball bearing 11 accurately into the inner cavity of the arc-shaped limiting groove 12, limiting and guiding the sliding path of the pulley 6. Simultaneously, the cooperation of the limiting pin 94 and the limiting groove 95 provides limiting and guiding functions for the lifting column 10, thereby improving the lifting column's... 10. Stability during the lifting process: The inner cavity of the fixed frame 8 is provided with a lifting column 10 that can be raised and lowered. The bottom of the lifting column 10 is embedded with a rolling ball bearing 11. The top of the track bar 7 is stamped and integrally formed with an arc-shaped limiting groove 12. The pulley 6 rolls and contacts the top of the track bar 7. The ball bearing 11 rolls and contacts the inner cavity of the arc-shaped limiting groove 12. The bottom of the support frame 4 is provided with multiple bolts 13. The top of the bolts 13 extends to the top of the sliding seat 2. The sliding seat 2 and the support frame 4 are fixedly connected by bolts 13.

[0015] Working Principle: In use, the user fixes the support frame 4 in the inner cavity of the sliding seat 2 using bolts 13. After assembling the galvanized door panel 1 on top of the sliding seat 2, the user moves the support frame 4 to the top of the ground rail 3, causing the surface of the pulley 6 to roll into contact with the top of the ground rail 3. The user then rotates the hexagonal rotating block 91, which in turn drives the threaded pin 92 to rotate. During this rotation, the threaded pin 92, through the interaction of its surface threads and the inner thread of the hexagonal nut 93, propels the lifting column 10. As the lifting column 10 moves downward, it causes the limiting pin 94 to slide within the inner cavity of the limiting groove 95. The lifting column 10 drives the ball bearing 11 into the inner cavity of the arc-shaped limiting groove 12. At this time, the surface of the ball bearing 11 rolls into contact with the inner wall of the arc-shaped limiting groove 12. During use, the galvanized door panel 1 drives the sliding seat 2 to slide on the top of the ground rail 3. During the sliding process, the sliding seat 2 drives the pulley 6 to roll on the top of the ground rail 3 through the support frame 4. This allows the support frame 4 to support and move the overall weight of the galvanized door panel 1 and the sliding seat 2. At the same time, the ball bearing 11 slides in the inner cavity of the arc-shaped limiting groove 12, causing the pulley 6 to move in a straight line along a predetermined trajectory, ensuring movement stability and effectively preventing the pulley 6 from derailing from the surface of the ground rail 3.

[0016] In summary, this galvanized door with an anti-derailment limiting structure, through the cooperation of the support frame 4 and the pulley 6, allows the sliding seat 2 to move along a specified path according to the distribution position of the ground track 3. At the same time, with the cooperation of the fixed frame 8, the adjusting component 9 and the lifting column 10, the ball bearing 11 rolls stably in the inner cavity of the arc-shaped limiting groove 12, thus achieving the purpose of simple and quick installation and effectively preventing derailment.
